DEVICE FOR REGISTERING ELECTRIC CURRENTS.l

SPECIFICATION forming part cf Letters Patent No. 655,703, dated August 14, 1900.

Application tiled December I6, 1899. 4Serial No. 740,541. (No model.)

To o/,ZZ whom t may concern:

Be it known that I, VICTOR G. FULLER, a citizen of the United States of America, residing at Toulon, in the county of Stark and State of Illinois, have invented certain designed for recording the length of time during which an electric circuit is closed.

The objects of the invention are, first,to provide a novel combination whereby the closing of a circuit by means of an. ordinary knife pattern-switch, either double or single pole, a spring of a timing mechanism is wound; second, to supply a lever under con` trol of an electric magnet whereby the closing of the switch-circuit releases the timing mechanism, thus starting the clock-movement, and whereby the opening of the circuit arrests the movement of the clock and holds it till the closing of the circuit again; third, novel means whereby the number of hours the circuit is closed and the clock runs is recorded by means of hands and dials; fourth, to provide novel means for the aut-omatic opening of the circuit ashort time before the clock-spring is unwound by means of a mechanical cut-out independent of the switch; fth, to provide novel means for closing the cut-out by the movement of the switclrarm in opening and closing the circuit at the switch, and, sixth, to provide a novel combination of the timing mechanism, indicators, electric switches, electric outputs,

winding and starting mechanism, suitably in` cased and under the control of an external' switch-arm and winding-lever.

Finally, the object of the invention is to provide a device of the character noted which will prove comparatively inexpensive, durable, and efficient.

With the above and .other objects in View the invention consists in the details of coustruction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail refer yence will be had to the accompanying drawings, `forming a part of this specification, wherein like characters denote corresponding parts in the several Views, and in which- Figure l is aface view of the meter-casing. Fig. 2 is a View of the mechanism with the casing removed( Fig. 3 is a sectional View with the automatic cut-out removed. Fig. 4t

wheel. l

In the drawings, 1 denotes a casing, which may be of any desired configuration, and 2 is one of the two sections forming a frame having bearings for the spindles, rico., the other section being a duplicate of the one shown.

The escapement 3, the balance wheel 4, the escape-lever 5, the spring-controlled main wheel 6, the minute-wheel 7, and the wheels 8 and 9, taking motion from theminute-wheel, being in construction the same as an ordinary clock-movement may not be described in detail. Mounted on the spindle with the minute-wheel are two pinions, the one back ,the casing and has mounted thereon a pinion a', `meshing with andtaking motion from an internal gear-wheel a2. wheel a2. is provided with a shoulder a3, en-

The periphery of the gaged by a spring-pressed dog a4. The dog is slidable in suitable guides on the combined winding-lever and switch-arm ctthrough which means the gear-wheel ctzis rotated. A cam-trip 0.6 is secured to the face of thecasing, and when the combined winding-lever and switch-arm has made electrical connection with the switch c7 the trip will have thrown the dog out of engagement with the Fig. 5 is a rear View ofV the combined winding-lever and switch-arm,

and Fig. 6 is a detail view of the winding-` shoulder of the wheel, and as the movement of the lever and the rotation of the wheel have served to wind the spring of the main wheel the indicating or timing mechanism starts and continues to run until the tripping device (to be hereinafter described) performs its functions.

The switch a7 has a connecting-wire ZJ leading to the line and a wire h2 connected to the cut-out switch h3 within the casing, the cutout arm b4 acting in conjunction with the cutout switch. A wire b5 connects the cnt-out arm and the magnet b, and a wire if' leads from the magnet to the load, th ns completing the circuit through the meter.

The winding shaft is provided with a toothed wheel c, meshing with alarger toothed wheel c. When the spring is wound, the wheel c will move in the direction of the arrow, and the insulated stud c2 thereon will engage the cut-out arm b4 and press it into contact with the cut-out switch, at the same time the switch a7 is closed and a circuit is completed from the wire b2 to the wire 297 through the cut-out switch and the magnet. As the magnet is energized it attracts an armature cZ, which is on a lever d', said lever having its end in engagement with a pin d2 of the balance-wheel when the circuit iscopen. As the magnet attracts the armature the end ofthe lever releases the balance-wheel and the timing mechanism starts.

A spring-pressed latch-lever e is pivotedy to a frame and has a shoulder engaging the cut-out arm when the circuit is closed, it being understood that the parts are suitably insulated, so that the current may pass only through the cut-out arm and the connections heretofore described.

When the timing mechanism is in operation the wheel c will rotate in a direction opposite to that indicated by the arrow and the insulated pin will pass around and abut the lever e. At the time the pin engages the lever the spring is unwound and the timing mechanism will cease to operate. If the current continued there would be no provision for keeping record. Hence it is desirable that the circuit be opened, and that result is automatically attained by the pin throwing the latch e out of engagement with the end of the cut-out lever, said lever being forced from the cut-out switch by a spring f. In oase the electric connection is broken or in the event of such diminution of the current as to reduce the strength of the magnet the armature would be released, its lever would engage the pin of the balance-wheel, and the timing mechanism would be stopped during the interruption of the current.

Having fully described the invention, what I claim as new, and desire to secu re by Letters Patent, is*
